US168ELD-AAA-000-RE

Overview

The US168ELD-AAA-000-RE is a single-chip solution designed for driving single-coil brushless DC (BLDC) fans and motors. It operates within a supply voltage range of 1.8 V to 6.5 V and features soft switching technology to reduce acoustic and motor noise. The device includes a full-bridge driver, integrated tachometer (FG) output, reverse voltage protection, locked rotor protection, and thermal protection. It is housed in a UTDFN-6 package.

Feature Summary

• Soft switching technology reduces acoustic and motor noise for smoother operation
• Integrated tachometer output follows Hall sensor signals for speed determination
• Comprehensive protection mechanisms including reverse voltage, locked rotor, and thermal protection

Applications

• Consumer class single-coil cooling fans
• Automotive onboard fan applications
• Vibration motors in mobile devices

Procurement Notes

Verify the specific suffix ELD corresponds to the UTDFN-6 package variant when sourcing. Confirm that the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Ensure compatibility with the 1.8 V to 6.5 V supply range for the target application design.

Selection Notes

Select this component for applications requiring low-noise operation in single-coil BLDC fan systems. The integrated FG output simplifies hardware monitoring by providing a direct signal connection. Consider the compact UTDFN-6 footprint for space-constrained designs in consumer electronics or automotive modules.
